6 Claims. 1

My invention relates to a combination carpenters tool, and more particularly to improvements in a combination carpenters tool embodying a framing square, universal square, protractor, bevel square, plumb and level tool, and center guages whereby stair horse lay-outs, skirting board lay-outs and roof pitch lay-outs may be readily and easily made. This application is a continuation in-part of my co-pending application Serial No. 145,290, and now abandoned.

Prior to the present invention, combination square and protractors have been manufactured and used, but heretofore, no square has been used which is readily adaptable for use by the novice by simplifying stair horse lay-outs, roof framing pitch lay-outs, and all roof coverings. Carpenters in the past have found it relatively difficult to obtain roof framing pitches as well as the complementary angles thereof. With my invention, I am able to use one indicia embodied together with my square so that roof framing pitches and their complementary angles can be easily and readily ascertained by a novice.

It, therefore, is an object of my invention to provide a square which will embody a bevel square, try square, break down framing square, combination square, protractor, level and plumb, lay-out tool for jambs, simplified tool for marking out hardware, centering tool for 2 x 4, 2 x 6, and 2 x 8s, center finder for various door thicknesses, unique tool for stair building, a tool for readily obtaining roof framing pitches, partition lay-out tool, and a beam compass.

Another object of my invention is to provide a device than can be used for any purpose a carpenters square can be used.

Another object of my invention is to provide an instrument to lay out stair horses and roof framing pitches without laborious calculations, charts, and reference books.

Another object of my invention is to provide an instrument of the type herein described which is simple to use.

Another object of my invention is to provide a tool that is light, easily foldable and simple to store and carry about, saving space and lightening the mechanic's tool box.

Other objects of my invention are to provide a device of the character described, which is sturdy in construction, economical to produce, and highly effective in operation.

With the above and related objects in view, my invention consists in the details of construction, and combination of parts, as will be more fully understood when the description is ready in 2 conjunction with the accompanying drawings, in which:

In use the proper disc is selected for the job to be done and mated on the shank 21 or the bolt D- the opening M of the disc E in alignment with the bore Nb of the bushing Ila. The pin 26 is positioned therein, and the thumb nut 22 is threaded upon the free end of the bolt D. The blade B is then moved until the notation on the indicia [0 for a particular operation of the job is aligned with a signal marker on the body A, whereupon it is locked in place by tightening the thumb nut 22 on the bolt/D. Oncetheinstrument has been setto amang-le the complementgthereof can be readily ascertained or marked oflby using the short removable arm C in place of the body A. Both angles are marked along the blade B.

In accor dance with the present invention-the adaptor block 43 is securedto the rear ofthe tool body A with" the guide blade: mounted. in the groove 48 between-the: adaptor block and: the tool body. This is accompl-ishediby' inserting the; head of the bolt Fl inthe' tool slot" 36 and tightening ath'umb mi-t 5-1 on the boltto m'aihtam the bolt and adaptor block: in-positiom A pair of lugs52'; 52 extending outwardly from the face of thead'aptorblock a'toppostteendsthereot engage the slot (and maintain the block in a predetermined position parallel with the tool body. The tool body is then placed on the upper surface of the skirt board as shown. in Fig. 12 with the guide blade in a vertical position and the thumb nut 51 is then securely, tightened to prevent rotary movement of the guide block 46 and maintain the blade in the vertical position. An elongated slot 50 centrally of. the guide blade permits the guide blade to be moved vertically withrespect to the tool body A and thereby fol-.- low the outline of the steps by sliding the tool body along the skirt board while at the same time the guide blade 44 is moved vertically with its pointer 44a in engagement with the steps.

In order to mark the outline of the steps on the skirt board, a tool or pencil holder 53 is provided mounted in a longitudinal slot 55 on the guide blade 44. The tool or pencil holder 53 has an opening 55 therethrough extending perpendicular to the guide blade in which a pencil 56 or other marking tool may be inserted. A thumb bolt 51 is inserted into the holder 53 in engagement with the pencil or marking tool as illustrated in Fig. to secure the pencil or marking tool in the holder. The holder 53 is secured to the guide blade at a predetermined distance above the point of the guide blade equal to the height of the rise of the steps so that as the point of the guide blade follows the outline of the steps, the pencil or marking tool in the holder 53 will copy the outline of the steps on the skirt board.

Figs. 18 to 22, inclusive, of the drawings illustrate the use of the carpenters layout tool of the present invention for marking a stair horse prior to cutting. In this embodiment of the present invention a removable blade 58 is provided which may be secured to the lower end of the blade B at right angles thereto by means of a clamp 59 secured to the blade B by a wing nut 6|. The upper end of the clamp 59 is provided with a downwardly and inwardly extending lip portion 62 which extends into a beveled slot 63 in the removable blade 58 to tightly hold the blade 58 against the end of the blade B. By changing the position of the clamp 59 in the slot 63, the relative position of the removable blade 58 with respect to the blade B may be varied.

In order to mark the stair outline on the stair horse, the adjustable blade B is positioned at an acute angle with respect to the tool body A with one end thereof projecting downwardly a distance equal to the length of the stair tread. Marks on the inner surface of the blade B as indicated at 64 in Fig. 21 may be used to determine the amount of projection of the blade B. The disc El which is rotatable with the blade B is set to indicate the height of the rise of the steps in inches and the removable blade 58 is then secured to the blade B in the manner previously described with the inner end thereof extending into the longitudinal slot in the tool body. The tool body is then positioned against the edge of the stair horse with the two blades, B and 58, in engagement with the stair horse as illustrated in Fig. 18 and a pencil or other marking device is used to mark the outline of the stairs on the stair horse.

From the foregoing, it will be observed that the present invention provides a novel layout tool which is of a relatively simplified construction and which has a greater variety of uses.
